74F86SC XOR Logic IC Equivalent & Substitute Parts

Part Overview

The 74F86SC is a 4-channel, 2-input XOR (Exclusive OR) logic integrated circuit manufactured by onsemi in 14-SOIC surface mount packaging. This component is classified as obsolete, making equivalent and substitute parts necessary for ongoing design support and production continuity. The 74F86 series represents a standard logic function widely available across multiple manufacturers, enabling straightforward substitution based on electrical and mechanical parameter alignment.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the 74F86SC is determined by strict alignment of electrical and mechanical parameters. All substitute parts must maintain identical logic function (XOR, 4 channels, 2 inputs per channel), supply voltage range (4.5V ~ 5.5V), output current specifications (1mA high, 20mA low), input logic thresholds (0.8V low, 2V high), and propagation delay (7ns @ 5V, 50pF). Package compatibility is evaluated based on the 14-SOIC form factor and surface mount mounting type. Substitutes are grouped by their relationship to the main part: direct manufacturer equivalents (identical package and electrical specifications), similar parts (same electrical performance with package width variation), and parametric equivalents (matching all critical electrical parameters with different packaging format).

Parameter Comparison

Engineering Selection Recommendations

SN74F86DR (Texas Instruments) is the primary direct substitute for the 74F86SC. This part maintains identical electrical specifications, package dimensions (0.154" width, 14-SOIC), and operating parameters. SN74F86DR holds Active product status with ROHS3 compliance and is supplied in Tape & Reel format, making it suitable for high-volume production environments.

SN74F86D (Texas Instruments) serves as a parametric equivalent with identical electrical performance and package type. This part is designated Last Time Buy status, indicating limited future availability. It is supplied in Tube packaging format rather than Tape & Reel, which may affect handling and assembly processes depending on production line configuration.

SN74F86NSR (Texas Instruments) is a similar substitute with matching electrical specifications but differs in package width (0.209" versus 0.154"). This wider package variant may require PCB layout verification to confirm mechanical compatibility with existing footprints designed for the standard 0.154" width. This part maintains Active status and ROHS3 compliance.

For new designs and production continuity, SN74F86DR is the recommended primary choice due to its Active status, standard packaging format, and exact dimensional match. SN74F86D may be considered as a secondary option if supply constraints arise, with awareness of its Last Time Buy designation. SN74F86NSR requires PCB footprint validation before implementation.

Frequently Asked Questions (FAQ)

Q: Can SN74F86NSR be used as a direct replacement for 74F86SC on existing PCBs?

A: SN74F86NSR has a different package width (0.209" versus 0.154"), which may cause mechanical incompatibility with PCB footprints designed for the 74F86SC. PCB layout verification is required before substitution.

Q: What is the difference between the Tape & Reel and Tube packaging formats?

A: Tape & Reel packaging is optimized for automated assembly lines with continuous feeding capability. Tube packaging is used for manual handling or lower-volume assembly processes. Both formats contain identical components; the difference is in delivery and handling method.

Q: Why is SN74F86D marked as Last Time Buy?

A: Last Time Buy designation indicates that Texas Instruments will discontinue this part after a specified date. Existing inventory may still be available, but future procurement cannot be guaranteed. SN74F86DR (Active status) is the recommended alternative for long-term supply security.

Q: Are all substitute parts ROHS3 compliant?

A: SN74F86DR, SN74F86NSR, and SN74F86D are all ROHS3 compliant. The original 74F86SC does not specify RoHS status in the provided data.

Q: Do all parts have the same electrical performance?

A: Yes. All listed substitutes maintain identical voltage supply range (4.5V ~ 5.5V), output current specifications (1mA/20mA), input logic thresholds (0.8V/2V), and propagation delay (7ns @ 5V, 50pF).

Q: What is the Moisture Sensitivity Level (MSL) rating?

A: All parts, including the 74F86SC and all substitutes, have MSL 1 (Unlimited), indicating no moisture sensitivity restrictions during storage or handling.
